They actually have a “silent mode” which is somewhat quieter, but still not silent (but slower it says) that’s really just a low humming. I really like them so far. Our intended project for the purchase is finally getting a treatment over the huge window above our front door that’s unreachable (split level) which we will hopefully be getting done this weekend, needing custom length curtains. It’s located in the direct path of sunrise and currently makes relocation during early morning TV watching necessary lol.
Also of note, much easier to use with grommet type curtains and our panels are shorter width so I just saftey pinned the top edges on the back so when it closes it pulls both panels. Really easy set up, and other than the backwards icon, really easy to use in Switchbot app, SmartThings and with Google Home.
